It just came to my mind that this little X is like a dumb light in
the car telling you the motor temp is too high... when it's too late
(or very late)... We'd be improving again, and innovating, if the
little square telling you text overflows would be a number (of line)
instead. Could be in a square. Could be whatever! But it would be
anything but dumb. And would help make a decision right away:
a. too many lines to adjust the layout, go back to the editor and
tell them to cut that many lines (and by the way, you sound smart
knowing that much about the problem! No more "cut a few, and it'll be
perfect" thing... who needs an approximation 10 minutes from the
b. 2-3 lines over, track a bit or suppress a subtitle
c. 10 lines over and this author will never accept a text cut, crop
the picture instead, crop it!
d. 20 lines and the same as 3, change the font and squeeze the
leading... oh! and yes, crop the pic, just a bit.
e. 300 lines over... well, at least you'll know it doesn't fit at all
and can ask "by the way who the hell did the layout and thought it'd
